C1 to C5 Alkylidene means methylene, ethylidene, propylidene, isopropylidene, butylidene, pentylidene, and the like.

Compounds (I) can be easily converted to the corresponding pharmaceutically acceptable acid addition salts, which are included within the scope of this invention. Representative acids which can form the pharmaceutically acceptable salts are organic acids such as acetic acid, citric acid, tartaric acid, methanesulfonic acid, malic acid, succinic acid, oxalic acid, salicylic acid, or the like and inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, or the like.

PREPARATION

Compounds (I) may be prepared according to the following scheme: ##STR7## (wherein M is hydrogen or alkali metal;

A is halogen or an ester residue;

B and D each is hydrogen or alkyl; and

X, m, Y, R1, R2 and R3 each has the same significance as given earlier)

(First Step)

This process may be carried out by reacting Compound (II) with Compound (III) in the presence of a base in an inert solvent at room temperature or under heating. Representative bases are sodium hydroxide, potassium hydroxide, sodium hydride, sodium amide, potassium amide, sodium ethoxide, potassium carbonate, and the like. Representative inert solvents are dimethylformamide, benzene, methanol, chloroform, dioxane, tetrahydrofuran, acetone, and the like.

The starting compound (II) is available, for example, by treating the ketone (IV) with N,N'-thionyldiimidazole or N,N'-carbonyldiimidazole for imidazole formation. The reaction is carried out in an inert solvent such as methylene chloride, chloroform, tetrahydrofuran, dioxane, benzene, acetonitrile, or 1,2-dichloroethane at room temperature or under cooling.

(Second Step)

The reaction of the starting compound (IV) with the compound (III) may be carried out in the same manner as in the First Step. Then the intermediate (V) is subjected to the imidazole formation in the same manner as in the above preparation of the starting compound (II).

Compound (2) (500 mg) is hydrogenated in 14% hydrochloric acid-methanol (5 ml) in the presence of platinum oxide in a hydrogen stream. After the absorption of 1 mole of hydrogen, the reaction is stopped. The reaction is filtered and the filtrate is concentrated. The residue is mixed with aqueous sodium hydrogencarbonate solution and extracted with methylene chloride. The organic layer is washed with water, dried over Glauber's salt and concentrated. The residue is crystallized from ethyl acetate-isopropyl ether to give Compound (7) (456 mg).
